Waste bin with an injection molded plastic body

Abstract

The invention relates to a the trash can ( 1 ) having an injection-molded plastic body ( 2 ) formed by ( 3, 4, 5, 6 ) and a bottom wall ( 8 ), that are positioned relative to one another so as to together delimit a cavity ( 15 ) having an opening ( 17 ) opposite the bottom wall ( 8 ), wherein each two mutually facing side walls ( 3, 4, 5, 6 ) merge into each other in an integral manner in a common corner ( 11, 12, 13, 14 ), and wherein an overhang edge ( 21 ) which runs around the opening ( 17 ) and has a collar ( 23 ) that projects radially outward from the side walls ( 3, 4, 5, 6 ) is provided on an upper side ( 16 ) of the trash can ( 1 ), wherein the collar ( 23 ) is also supported on the side walls ( 3, 4, 5, 6 ) by ribs ( 28, 51, 52, 53, 54, 55, 56, 57, 58, 59 ) spaced along the overhang edge ( 21 ), and wherein the injection-molded plastic body ( 2 ) is partially reinforced with at least one laminar surface reinforcement ( 35 ) such that the wall thicknesses of the trash can ( 1 ) are reduced as a whole while maintaining the same capacity.

1 . A trash can having an injection-molded plastic body formed by
 side walls,   a bottom wall positioned relative to the side walls so as to together define a cavity having an opening opposite the bottom wall, each side wall integrally merging into the adjacent side walls at common corners,   an overhang edge that runs around the opening and has a collar projecting radially outward from the side walls on an upper side of the trash can and also supported on the side walls by ribs spaced along the overhang edge, and   a laminar surface reinforcement partially reinforcing the injection-molded plastic body such that the wall thicknesses of the trash can are reduced as a whole while maintaining the same capacity, the laminar surface reinforcement extending over the entire length or at least over more than half of the front side wall. having a thickness more than 10% thicker than unreinforced regions of the side walls, and forming a three-dimensional surface structure inside the injection-molded plastic body of the trash can.   
     
     
         2 . The trash can according to  claim 1 , wherein the laminar surface reinforcement comprises a flat material thickening. 
     
     
         3 . The trash can according to  claim 1 , wherein the laminar surface reinforcement extends into the corners of the trash can that are adjacent the front side surface. 
     
     
         4 . The trash can according to  claim 1 , wherein the laminar surface reinforcement extends into edge regions of front side wall and/or of lateral side walls that are adjacent corners. 
     
     
         5 . The trash can according to  claim 1 , wherein the laminar surface reinforcement has a larger width in the front corners in the circumferential direction of the trash can on an upper side of the trash can than on the underside of the trash can. 
     
     
         6 . (canceled) 
     
     
         7 . The trash can according to  claim 1 , wherein the laminar surface reinforcement forms a U-shaped surface structure inside the injection-molded plastic body of the trash can. 
     
     
         8 . The trash can according to  claim 1 , wherein the laminar surface reinforcement comprises a flat upper belt on the upper side of the trash can that connects the corners adjacent the front side wall to each other. 
     
     
         9 . The trash can according to  claim 8 , wherein the flat upper belt extends into regions of the overhang edge. 
     
     
         10 . The trash can according to  claim 1 , wherein the laminar surface reinforcement extends over a front overhang edge segment. 
     
     
         11 . The trash can according to  claim 1 , wherein the laminar surface reinforcement is supported by a grating structure. 
     
     
         12 . The trash can according to  claim 1 , wherein the ribs spaced along the overhang edge have different rib thicknesses. 
     
     
         13 . The trash can according to  claim 1 , wherein the ribs on a front overhang edge segment have a greater rib thickness than other ribs of the overhang edge. 
     
     
         14 . The trash can according to  claim 1 , wherein the ribs positioned on a front overhang edge segment have a thickness at least more than 10% greater than other ribs of the overhang edge. 
     
     
         15 . The trash can according to  claim 1 , wherein the ribs provided above a front corner on the overhang edge have a rib thickness smaller than ribs positioned on the front overhang edge segment, but greater than other ribs of the overhang edge. 
     
     
         16 . The trash can according to  claim 1 , wherein the ribs positioned above a back corner on the overhang edge have a rib thickness smaller than the ribs provided on the front overhang edge segment and positioned above a front corner, but greater than other ribs of the overhang edge.
